Limitations and restrictions

On-hook dialing can result in users hearing the DTMF from the key press in the handset. The tones are heard

if the handset is picked up while the last digit is pressed. If users pick up the handset after pressing the last

digit, they will normally not hear any DTMF.

If the PC attached to the PC port of the phone is using IPv6, we recommend that the PC Voice LAN access

be disabled. This ensures that the PC can connect to the Voice VLAN.
